651-93-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 651-93-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 651-93:
(5*6)+(4*5)+(3*1)+(2*9)+(1*3)=74
74 % 10 = 4
So 651-93-4 is a valid CAS Registry Number.

A Synthesis of Novel Perfluorodienes

Briscoe, Mark W.,Chambers, Richard D.,Mullins, Steven J.,Nakamura, Takayuki,Drakesmith, Frederick G.

, p. 1127 - 1128 (1990)

Oligomers of perfluoroalkenes are converted to dienes in good yields, using sodium amalgam; these dienes are highly susceptible to nucleophilic attack and can be excellent sources of heterocycles.

Fluorinated di-enes

Chambers, R. D.,Vaughan, J. F. S.,Mullins, S. J.,Nakamura, T.,Roche, A. J.

, p. 231 - 234 (1995)

Fluorinated di-enes may be obtained by the defluorination of some oligomers of F-alkenes and -cycloalkenes using tetrakis(dimethylamino)ethene.These di-enes are very susceptible to nucleophilic attack.Nucleophilic epoxidation of (4) gives a new diepoxide which undergoes a novel ring-opening reaction.Di-ene (4) forms cyclopentadienylide derivatives with di-functional carbon nucleophiles and a cyclopentadienylide salt (17) is obtained in a remarkable 'one-pot' reaction from hexachlorobutadiene. (4) (17) - Keywords: Fluorinated di-enes; Tetrakis(dimethylamino)ethene; Defluorination
